Abstract :
A novel 6-DOF parallel haptic device is presented, which is characterized by large workspace, high rigidity, compactness, simple kinematics and easy construction. Its mechanism is composed of three sub-chains, each of which is attached to the base plate through a pin joint and the top plate through a spherical joint. The sub-chain is kinematically equivalent to the pantograph linkage and designed to solve the difficult problem of motor-fitting. The spherical joint belongs to the ball-in-socket type but has much larger workspace than regular ones. The forward and inverse kinematic analyses of the mechanism are performed, and Jacobian matrix is derived. The workspace is analyzed with a new scanning search method of the spherical coordinate searching algorithm, by which the intersections of multi-connected domains are readily obtained
